Rebooting didn't help.  It also affected all 3 of my networked computers (which use a shared drive on one of the computers).

I was starting down the path of Tool Hub when Lacerte support answered the phone.   Fortunately she agreed with Tool Hub and away we went.  It took a few minutes to force the re-install (and required a reboot of the computer), but it fixed not only the computer I was working on, but the 2 others as well.

Support didn't know why it happened.  I suspect a corrupted download, but who knows. 

Back to tax returns.  Thanks, abc!
